[ANN][BURST] Burst | Efficient HDD Mining | New 1.2.3 Fork block 92000

[SpeedDemon13]

to the DEV ... i musst ask again...

i have this: (overlapping is only bad for diskspace?)
run_generate.bat <address> 0 500000 4000 4
run_generate.bat <address> 500000 500000 4000 4
run_generate.bat <address> 1000000 500000 2000 4

or should i use this?
run_generate.bat <address> 0 500000 4000 4                (128GB)
run_generate.bat <address> 500001 500000 4000 4        (128GB)
run_generate.bat <address> 1000001 500000 2000 4      (128GB)

and second.
if i have i big gap like this.. do i need ploting the missing file for correct mining or can i move to the next plot?
i mean do i ned a coherent chain ??
1. run_generate.bat <address> 0 500000 4000 4                (128GB)
2. (missing file of 128GB)
3. run_generate.bat <address> 1000001 500000 2000 4      (128GB)
4. (next plot: 1500001 500000 2000 4)

Either is fine. Technically, 500000 plots starting from 0 is 0 - 499999, so the second has a gap of 1 in between the first 2, but that doesn't matter.

Overlapping is bad since it calculates to the same result in multiple places, wasting disk space and doing unnecessary work.
There is no problem with having gaps.
This:
run_generate.bat <address> 0 500000 4000 4
run_generate.bat <address> 500000 500000 4000 4
run_generate.bat <address> 1000000 500000 2000 4
is just as good as this:
run_generate.bat <address> 0 500000 4000 4
run_generate.bat <address> 5000000000 500000 4000 4
run_generate.bat <address> 9898000000 500000 2000 4

So, staggering is best implemented on the same drive. But on multiple drives, you can start from each one at 0 if you wanted to with one large plot for each. If I'm understanding this correctly. I notice that it seems that most people are more successful making smaller multiple plots on hdd's than one larger one.

So, the formula for calculating nonce size is this: x=Nonce size

                                                                  f(x)=hdd size in GB

                                                                  (256x)/10^6=f(x)

                                                                   x=[f(x)*10^6]/256

its not 10^6 but 1024^2

That's an approximate, but so this would be the end result then: x=[f(x)*1024^2]/256

you should write it f(x) = x*1024^2/256 (for correct mathematical expression), where x is disk size in GB and f(x) is nonce count

anyway, more correct and simple equation form is f(x) = x*4096 , where x in GB of disk size

But yeah I should have reverse that. Not wrong either way depending what is selected as the range or domain, that's the beauty of Algebra. So, to even clean it up more, it's simple this: f(x)=4096x . Thanks

Wait, how is this work globaly verifiable by peers, how do you know my miner isn't modded to just relay random data until something stivks and I get a block ?

I also want to know the answer of this question. I dont have the time to debug the program now, but i think that admin will ensure us that everything is ok.

And also why i have to send my passphrase to the central server/pool. It,s not secure... That way every pool admin will have the accounts of every user, which is mining...I don't want to speak about hackers... Why dont you send the Burst adress

this is from MinerCom.java

Code:

		else if(message instanceof MinerSupr.msgSubmitResult) {
			System.out.println("Submitting share");
			try {
				ContentResponse response = client.POST(addr + "/burst")
						.param("requestType", "submitNonce")
						[b].param("secretPhrase", ((MinerSupr.msgSubmitResult)message).passPhrase)[/b]
						.param("nonce", Convert.toUnsignedLong(((MinerSupr.msgSubmitResult)message).nonce))
						.timeout(5, TimeUnit.SECONDS)
						.send();
				String submitResult = response.getContentAsString();
				System.out.println(submitResult);
			}
			catch(Exception e) {
				System.out.println("Error: Failed to submit nonce");
			}
		}

i think its push result to your wallet, so yes it need ur passpharase, and ur wallet is to be expected to run locally, we dont have pool implementation yet

Wait, how is this work globaly verifiable by peers, how do you know my miner isn't modded to just relay random data until something stivks and I get a block ?

my simplified answer is, you broadcast ur account number and ur selected nonce to network, these two numbers can be verified into deadline value, so yes you can just broadcast any data (nonce and account number), but i doubt you want to broadcast random account number since you wont receive ur reward, and for nonce yes it is just random value, we select it which one has lowest deadline value

edit : i think nonce is not so random, because they are relevant scoop for each block (depend on previous block hash), i am not sure, we need to read the implementation, its just based on OP post

when the pools come out, its difficulty will increase more faster ,now only just 5 days since the coin came out,when the difficulty increase until you can only less than 1 block/TB/Month, then the coins value will be enhanced

i think its already expensive, since we dont have fractional coin here
so coin cap of 2,158,812,800 coins is similar to 21 coin cap of bitcoin style shitcoin ( because of 8 digits fractional )
so i expect the price will be 100 sat btc to 1 burst ( 1million burst = 1 btc )

xcn, come out for three weeks,  has 1.8billion coin, its total number is similar to burst, two weeks ago ,it was mined with cpu, its highest price is 0.00012btc, now , with gpu miners come out, its diffculty falls very fast, and the value falled very fast, and now steady at 0.00002btc for a long time, which means ,even at the lowest price, it still can reach 2000 sat btc,,total number can not decide a coin's value, it was determined by difficulty and popularity

what is this address

Code:

BURST-2222-2222-2222-22222

lot of transactions sent to that address, is it burn address ?

edit : i think nonce is not so random, because they are relevant scoop for each block (depend on previous block hash), i am not sure, we need to read the implementation, its just based on OP post

it seems that the dev hashing every 256KB and compare it with the announced hash =>(,"generationSignature":"b51990f5dce09d649397d19380483003bf2906d3
cbc1678ad5220e1a0e4ea48a"})

after that send the best value. If you have more 256KB blocks, you will have better chanse to find best value.

The algorithm is not so simple as i describe it.

The question is - Is it possible to run it into mining rig with 10 GPUs and to generate the nounce lifetime?

[SpeedDemon13]

I created a thread specially for mining Burst/PoC coins. It has a spreadsheet to share data to the community. Here's the link: https://bitcointalk.org/index.php?topic=740158.new#new

Hope the dev can put this on the OP.

lifetime ? do you mean "on the fly" without pre-generated data?

you think poc miner won't waste electricity because now the difficulty is not high ,,only five days out with no logo and no pool
!  how big diffculty can be,,when pools come out, those who mine the cpu and gpu based on join this, if you can only mine with 1000 burst /TB/week , would you sell at 100sat? poc needs electricty too, and what's important, it will damage your disk! every disk has the top read and write times, if you can only mine with 1000 a week ,that is ,  4000 a month, 4000 * 100 sat = 0.0004btc, then ,would you willing to sacrifice your disk for just 0.0004btc a month?

if you have  good cpus, you will choose cpu based coin only, like XMR,etc. and you will not use your cpu to mine the X11 ,X13,X15...if you have good gpus, you will choose gpu based only, like darkcoin, X11based, X13 based,,..look at the forum, so many these coins, and you will not choose your gpus to mine the scrypt or sha256 based coin to ,because these have asic machines,, now, what's the point is they all have hdd, little or large, when the burst have a wonderful logo, have several steady pools, until lunch several exchange platforms, every one will kown there is a coin which can be mined with hdd,,  burst is the only  coin which can mined with hdd, at least now,, if you are miners in them,would choose to mined the burst when you still can mine the gpu or cpu based coin? at that time, how can you have confidence of you can still mine this coin several blocks a day?

Found a block about 26 hours since last found block on 800gb. 

[uray]

lifetime ? do you mean "on the fly" without pre-generated data?

exactly

it is possible, but considering the size of each nonce 256KB compared to GPU style about 4-16Bytes, the possible combination is too huge.

assuming speed of generating hash on GPU is 1 MH/s, this means we can try 0.24 Giga-Nonce per block time

compare it if we have 4 TB disk, it store 1 Giga-Nonce which we can try all of them per block time, resulting
in storing nonce on disk is faster 4x than hashing it "on the fly" on GPU, ofcourse my assumption of 1 MH/s is wild guess...

before we have exact value how much nonce can be generated on GPU per seconds, we can't come to conclusion which one is more efficient, hash on the fly or pre-generate it on disk

[Sy]

Pre generated saves alot of power though so it really comes down to gpu speed

So is it better to have one big plot on a hdd, or many plots?

diff increased 65% in last 24h ... that means network hd capacity rises by the same factor ... correct?!

So is it better to have one big plot on a hdd, or many plots?

should make no difference ... but for every block, some data has to be read by miner from every plot file, so if you have a lot, thats slower than reading from one file ... but 1-10 or some more are no problem.

if you once need more space for 'real' data, its a good thing to have multiple plot files ... so you can simple delete one of them :-)

[paulthetafy]

If anyone is interested, the conclusion of my test to see if I could speed up plot generation by farming it out using cluster/cloud computing is:
Yes it can be done, but it is probably not worth it.  This is what I did using Amazon EC2...

First I created a single instance (2 core) to act as the server for the plot storage and also act as the wallet server / miner.
This instance had a 1TB Elastic Block Store volume attached to it (1TB is max EBS volume size on AWS). I made this volume available to the network using NFS

I then created a "plot generator" instance with much higher CPU capacity (C3.xlarge 8 core). I mounted the shared volume so it appeared like a local disk and started creating 10GB plots
I then created a few scripts so that upon startup the instance would auto-mount the NFS volume, figure out what the last used nonce range was, and start mining from the next 10GB plot
Finally, I created an image of this instance and spooled up 100 more instances like it (spot rates, nice and cheap).

To begin with it all looked great but I soon hit the bandwidth limit of the instance I was using as the server.  In essence the server didn't have enough network bandwidth to cope with all of the data being copied to it.  This restricted plot creation to a little over 100GB / hour.  Changing the instance type of the server instance to one with a "high" network performance got this up to around 400 GB/hour.  If I had have left it running I would have created all 1 TB of plots in 2.5 hours, at a cost of around $20.  This could have been repeated or even parallelized to create several 1TB volumes full of plots in a relatively short amount of time.

After all the fiddling about getting it working, I spent around $70 testing this stuff out, only to conclude it was too much hassle.  And as OP said earlier, the cost of EBS storage on AWS is too high to make this a viable long term mining option.  That said, had I have done all of this on day one, I would have scaled the process out and had 10TB+ up within the first few hours and dominated the mining.  Good to know I have the process licked for the next PoC coin

Unfortunately I STILL don't have any BURST as I don't have any spare capacity at home so haven't been able to mine at all  So if anyone would like to donate some coins to offset the cost of testing all of this, my address is BURST-WADY-CBZE-HSJU-2NH5G

Many thanks!
